Shimpo did not set out to make potter’s wheels. By its own account, potters came to it for its speed control.

The parent company’s own history is exact. Shimpo Industrial Corporation was established in Kyoto in April 1952. Its first potter’s wheel, the RK-1, followed in November 1958. In October 1969 it won the Deming Prize in the small and medium enterprise category — Japan’s best-known award for quality control — a date sometimes given elsewhere as 1972, which the company’s own record does not support.

The ceramics business tells the origin from the other side. Shimpo, it says, got into wheels when it “was asked to incorporate our patented mechanical variable speed drives into early versions of the Pottery Wheel.” That is the company’s account, and it explains the brand: Shimpo was a maker of drives and speed reducers first, and the wheel was a place to put one. The quality that potters still buy a Shimpo for — a smooth, controllable, quiet turn — is the gearbox company’s speciality.

In February 1995 the motor group Nidec acquired Shimpo. The company became Nidec-Shimpo in October 1997 and, on 1 April 2023, was renamed Nidec Drive Technology Corporation. The industrial business no longer carries the Shimpo name at all. The North American ceramics arm, which dates from Chicago in 1974, moved to Glendale Heights, Illinois, in 2017.

In 2018 the owner asked for the Shimpo logo to come off the product. Seven years later the ceramics line changed hands.

The ceramics site records the moment plainly: “In 2018 NIDEC requested all product groups to be unified by including its name on all products and removing the familiar SHIMPO logo and pottery symbol. Look for the color green and NIDEC at major conferences and events.” It is rare to find a brand explaining, on its own website, that its owner has asked it to stop using its logo. For a few years the best-known potter’s wheel in many American classrooms was sold under a motor company’s name.

Then the ownership moved. In its exhibitor listing for the National Art Education Association’s 2026 convention, the company described itself as “Nidec/Daido” and said: “In the spring of 2025, Daido USA acquired Nidec-Shimpo Ceramics, including its full line of manufactured equipment such as pottery wheels, pugmills, and banding wheels.” The ceramics site’s footer now reads “Copyright © SHIMPO CERAMICS Distributed by Daido,” a recent job advertisement is headed “Shimpo Ceramics dba Daido USA, Glendale Heights IL,” and Daido USA describes itself as consisting of two businesses, factory automation and ceramics.

We should be careful about what that does and does not establish. It is Daido USA’s own description; we did not find a filing or a press release from either side, so we cannot say whether this was the purchase of a business or a distribution arrangement described generously, and we did not establish who owns Daido USA. We write it as Daido USA says it is. What we can say is that the name came back: the logo file the ceramics site now serves is named for Shimpo alone.

The wheel carries no country of origin in its manuals. Its former parent’s factory list names one plant for pottery equipment — in China.

Nidec Drive Technology publishes a list of its production sites and what each makes. Exactly one entry includes pottery equipment (陶芸機器) among its products: Nidec Drive Technology (Zhejiang), in China, listed as making speed reducers, automated guided vehicles, measuring instruments and pottery equipment. The Japanese plants on the same list — Komagane, Ueda and Ritto — do not mention it.

That is a strong pointer, not a nameplate. The manuals we read for the VL-Whisper, VL-Lite and Aspire contain no “Made in” wording, and the factory list is Nidec’s, published by a company that, on Daido USA’s account, no longer owns the ceramics line. So the precise statement is this: Nidec’s published production-site list names a plant in Zhejiang, China, as its pottery-equipment factory. We do not claim that every Shimpo wheel on sale today was made there.

The wheel is also only part of what changed hands. The American catalogue runs to pugmills — the NRA-04, NRA-04S, NVA-04S and NVS-07 — plus slab rollers and banding wheels, which is exactly the list Daido USA named. And “a Shimpo wheel” means different machines on different continents: the European site sells its own line-up, including the RK-3E, RK-3D, Whisper-T, RK-55 and RK-5T, alongside models American potters would not recognise. One name, two catalogues. The 2025 acquisition statement comes from the American side, and we found nothing saying who now runs the European one, so we do not guess.

It matters because of what the brand still trades on. A Japanese name, a Kyoto founding, a Deming Prize: buyers read all of that as a promise about where the machine was built. The documents promise something narrower — about who designed the drive, and whose quality system it came out of.

The flagship is the VL-Whisper: a half-horsepower, 400-watt brushless direct-drive motor, rated to centre 100 pounds of clay, 0 to 250 rpm, with a five-year warranty. Shimpo says “we can say the quietest wheel in the potter’s wheel market.” And its product page carries a warning we did not see from anyone else in this round: because of the magnet motor, the wheel “may be harmful to a person who has a pacemaker.” We did not find a UL or ETL listing statement in the manuals or on the site.

The one colour in this round that an owner specified in writing.

Shimpo’s tagline is short and on-message: “We keep you turning.” It is a drive-maker’s promise as much as a potter’s — continuity of rotation is exactly what a speed reducer is for.

The colour story is the oddest in the round. Every other maker here chose its own palette. Shimpo’s ceramics customers were told what colour to look for — “Look for the color green and NIDEC” — in the same sentence that announced the removal of the Shimpo logo and its pottery symbol. The green was the parent’s, applied to the child.

For this guide we use a wheel green and a pale celadon with a quiet gothic — a deliberate nod to that sentence, since green is the colour the brand’s own site told potters to look for. It is still an unofficial interpretation, not the colour value of any Nidec, Daido or Shimpo mark, and nothing of the logo or pottery symbol is reproduced.

Keep Shimpo’s identity on hand — save it to a board in the Made Good inspiration library.
